Embodiment

[0062] In this example, see figure 1 , a PON access system based on the third version of the IGMP multicast implementation method, the PON access system includes a main control board and four line cards, the main control board includes a CPU and a switch chip, Each line card includes a CPU, a switch chip and 8 PON ports, and the implementation method includes the following steps for the main control panel and each line card:

[0063] Step 100: Set the working version of the PON access system to the third version of IGMP and switch the switch chip of the main control board and the switch chips of all the line cards to the third multicast state.

[0064] Step 101 , for each PON port of the line card: the line card receives the multicast member report sent by the user terminal through the PON port, and the CPU of the line card generates a first multicast member information table according to the multicast member report.

[0065] The first multicast member information table inclu...

Abstract

The invention discloses a PON access system and a method for realizing multicast thereof. The method includes: S1, the CPU of the line card generates a first triple through the first multicast member information table; S2, the The switching chip of the line card receives and saves the first triplet sent by the CPU of the line card; S3, the CPU of the master control panel generates a second triplet through the second multicast member information table; S4, the master The switch chip of the control panel receives and saves the second triplet sent by the CPU of the master control panel; S5, the switch chip of the master control panel sends a multicast through the port of the master control panel specified in the second triplet The data is sent to the line card; S6. The switching chip of the line card sends the multicast data to the user terminal through the PON port specified in the first triplet. The PON access system of the present invention can realize multicast based on the third edition of IGMP, and can realize multicast communication more accurately and efficiently.

Description

technical field [0001] The present invention relates to a PON (Passive Optical Network: Passive Optical Network) access system and a multicast implementation method based on the third version of IGMP (Internet Group Management Protocol: Internet Group Management Protocol). Background technique [0002] IP (Internet Protocol: protocol for interconnection between networks) multicast technology utilizes TCP / IP (Transmission Control Protocol / Internet Protocol: Transmission Control Protocol / Internet Internet Protocol) protocol to realize point-to-multipoint efficient data transmission in IP networks communication. IP multicast technology has the advantages of high data transmission efficiency, high utilization rate of network broadband, low possibility of network congestion, and the ability to avoid possible broadcast storms in broadcast and unicast. IP multicast technology is widely used in multimedia conferences, Real-time data transmission, games and many other aspects. The ...
